Hell nah. I'm an atheist but I'm open to the possibility of ghosts after an experience my friend had. Didn't have anything to do with an ouija board but I'll post it here anyway.
This was several years ago, one of my close friends was in a relationship at the time. He's a diehard atheist who refuses to believe anything supernatural, not even open to the possibility of it. His girlfriend lived in a fairly large mansion not that far away from his house. She had been complaining about weird noises when she was home alone but my friend dismissed it as her imagination. She also dismissed it as her imagination or natural causes such as the wind causing the wooden floors to make noises, doors opening, closing, ...
One day she calls my friend at around 10PM screaming in tears about how she was home alone and her piano started playing by itself it another room. She locked her room and barricaded the door and asked my friend to quickly get over there.
He hops on his bicycle and goes over there, calls her again to let her know he's there and she needs to come unlock the door. At this point my friend thought it was kinda funny and didn't really believe anything weird was going on.
They go back to her room and as he's calming her down, the piano starts playing again in another room. My friend clearly heard it as well. They locked and barricaded the door again and then they hear footsteps on the wooden floors. A few doors opened and closed. They stayed in that room until the parents came home several hours later.
Despite his prior beliefs, this event scared him so much he's now open to the possibility of ghosts existing. Before that he was about as skeptical as it gets. He actually broke up with her because he didn't want to go to that house ever again.
The girl has moved since then.
